Abstract
The present invention provides a kind of method for carrying out microfine chalcopyrite flocculation sedimentation using mixed flocculation agent, belongs to Flocculating Settling Technology field.This method prepares mixed flocculation agent first, and mixed flocculation agent is mixed by anionic polyacrylamide, carboxymethyl cellulose, polyaluminium sulfate.Above-mentioned mixed flocculation agent and milk of lime is added in microfine chalcopyrite after flotation, is further dehydrated after flocculating setting.2g/t-8g/t of the dosage of the mixed flocculation agent relative to ore pulp weight.The present invention improves the sinking speed of chalcopyrite, reduces lime consumption, improves the underflow density of concentrator, can solve chalcopyrite very well and run muddy phenomenon, increase economic benefit.Formula production is simple, operating cost is low, effect is obvious.
Description
Technical field
The present invention relates to Flocculating Settling Technology fields, particularly relate to a kind of application mixed flocculation agent progress microfine chalcopyrite
The method of flocculation sedimentation.
Background technique
Jiujiang, Shangrao, it is one very heavy in Anqing, Middle_Lower Yangtze metallogenic belt collection area, Tongling China Deng Dishi
The mineral deposit wanted, this kind of mineral deposit be a copper, sulphur, iron symbiosis large-scale synthesis mineral deposit, mine is main with copper, sulphur, iron resource
Object is exploited, domestic this kind of resource is also more elsewhere, wushan Copper Deposit, Ores At Chengmenshan Copper Mine, the Dexing copper in typical such as Jiangxi
Mine；Technology of Anqing, the Jingxian County gold ancient cooking vessel mining industry in Anhui etc..
By the way that microfine chalcopyrite, since quality is small, large specific surface area causes specific grain surface high, adds its mine
There is oiliness medicament etc. on object surface, therefore is easy to form floating state.Therefore microfine chalcopyrite carries out the process of concentrating and precipitating
In, effect is poor, and easy race is muddy, wastes a large amount of chalcopyrite concentrate product, will be a heavy losses to bargh.
Currently, flocculant majority uses single organic or inorganic flocculating agent.It is not very using inorganic flocculating agent effect
Ideal then generates biggish side effect to subsequent filtering using high polymer coagulant.For example, the problems such as ceramic panel blocks,
Increase filtering cost.
Summary of the invention
The flocculation of microfine chalcopyrite is carried out the technical problem to be solved in the present invention is to provide a kind of application mixed flocculation agent to sink
The method in shallow lake.
This method comprises the following steps:
(1) mixed flocculation agent is prepared: in mass ratio by anionic polyacrylamide, carboxymethyl cellulose, polyaluminium sulfate
For (1~2): (2~4): (3~6) are mixed, and mixed flocculation agent is made；Middle anionic polyacrylamide, carboxymethyl cellulose
Element, polyaluminium sulfate are all technical grade product；
(2) it prepares milk of lime: quick lime and water being blent according to mass ratio 1:3, and are sufficiently stirred in agitator,
Milk of lime is made；
(3) it is according to ore pulp mass ratio per ton by the milk of lime of the mixed flocculation agent of step (1) preparation and step (2) preparation
(6~12): (1000~3000) addition carries out flocculating setting.
Wherein, anionic polyacrylamide is equably thrown and is sprinkling upon in tap water in step (1), is subject in 40-60 revs/min
Speed stirring makes macromolecule be completely dissolved in water, and proportion mass concentration is 0.1%.
Polyaluminium sulfate is prepared according to concentration 5~10% in step (1), and stirs 50-100min.
Carboxymethyl cellulose is that 0.5-1% is prepared, and stirs 50-100min according to concentration in step (1).
Ore pulp is particulate chalcopyrite ore pulp in step (3), and chalcopyrite granularity is -38 μm and is greater than 80%.
The advantageous effects of the above technical solutions of the present invention are as follows:
1. the present invention selects to act in upper method using polymorphic type flocculant cross-mixing in medicament, such as high polymer coagulant
Potent fruit and inorganic flocculating agent production application reliability etc..
2. the present invention optimizes regime of agent in assorting room, gradation is used in the sedimentation of fine-graded chalcopyrite
Grade sedimentation, (1 μm of <) uses polymeric anion flocculant on superfine grade particles, and in thin grade using inorganic flocculating agent into
Row sedimentation (1~40 μm).
3. this method compared with well-known technique, not only ensure that the precipitating of coarse grained chalcopyrite, while thin also in guarantee
Effective sedimentation of particle, reduce copper concentrate run it is muddy, achieve good economic benefit.
Detailed description of the invention
Fig. 1 is the method and process flow chart of the invention that microfine chalcopyrite flocculation sedimentation is carried out using mixed flocculation agent；
Fig. 2 is precipitation test result in the embodiment of the present invention.
Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The present invention provides a kind of method for carrying out microfine chalcopyrite flocculation sedimentation using mixed flocculation agent, process flow
As shown in Figure 1, comprising the following steps that
(1) mixed flocculation agent is prepared: in mass ratio by anionic polyacrylamide, carboxymethyl cellulose, polyaluminium sulfate
For (1~2): (2~4): (3~6) are mixed, and mixed flocculation agent is made；
(2) it prepares milk of lime: quick lime and water being blent according to mass ratio 1:3, and are sufficiently stirred in agitator,
Milk of lime is made；
(3) it is according to ore pulp mass ratio per ton by the milk of lime of the mixed flocculation agent of step (1) preparation and step (2) preparation
(6~12): (1000~3000) addition carries out flocculating setting.
Embodiment 1
Ore pulp property analysis is carried out to Yangtze river basin Tong Liuxuan factory scene flotation of sulfur concentrate, tests pH values of pulp, is carried out
Wet screening (sieve takes 200 meshes), dry, weighing.It is as follows to measure ore pulp relevant nature:
1 chalcopyrite concentrate ore pulp property of table
Sample preparation mixes division after being filtered drying to the undersized product of wet screening, and sample ore is analyzed with laser particle size analyzer
